Orthopedic technology
The software that prints personalized casts
Gero is a technology platform for personalized orthopedics. A tablet scan goes in; an automatically designed, 3D-printed cast comes out, fitted to one patient.

Patient treatments on the Gero platform
The Gero platform
Software is the product. The cast is its output.
Four layers built in-house turn a clinic visit into a manufactured, patient-specific medical device, with no plaster room and no specialist skills.

Gero App
An iPad app with a structured-light sensor captures the limb in under two minutes, accurate to 1 mm. The clinician enters patient details, picks the cast type and orders in the same visit.

Design Engine
Computer vision finds 21 anatomical keypoints, builds a hand skeleton and extracts the limb's contours. A parametric model then fits the cast to the patient and applies the chosen pattern.

Cloud platform
A serverless backend runs orders, clinics, payments and patient notifications. An admin console gives the team full control of the catalogue, orders and support.

Production network
Print-ready files go to certified additive-manufacturing partners. Casts are printed, finished and shipped to the clinic within 3 days.

From scan to model
One visit, one tablet, one order
The clinician scans, reviews the 3D model on screen and taps Done. The design engine takes it from there: the cast is generated, checked and sent to print automatically.

Traditional casting vs. Gero, side by side
Filmed with Schneider Children's Medical Center: follow 9-year-old Amy from her first visit to cast removal, and see what changes for the patient and the clinic team.
Made by additive manufacturing
From powder bed to patient
Every Gero cast is printed layer by layer from a file our software generated for one patient. Drag the handle to see a cast straight out of the printer, and the finished product.
Industrial powder-bed printing makes the open rhombus lattice possible: strong where the fracture needs support, open everywhere else for air and water.

What physicians say
Trusted by orthopedic surgeons
Gero3D technology has delivered exceptional results in our fracture and post-surgery treatments, offering custom-fit comfort that surpasses traditional options. The positive recovery outcomes reflect the patient-centric design and effectiveness of Gero3D's products.
Prof. Mark EidelmanDirector, Pediatric Orthopedics UnitGero3D's personalized casts have significantly enhanced our patients' recovery experience, especially for young patients facing typical challenges. The ability to tailor each cast has improved comfort and healing consistency, showcasing the benefits of individualized care.
Using Gero3D's technology, I've observed excellent stabilization and patient comfort in post-surgical care. After breaking my own hand, I experienced firsthand the lightweight, breathable design, which provided convenience and effective healing with minimal restrictions.
What patients say
Healing without putting life on hold
When I broke my left hand, I was worried about dealing with an itchy, bulky cast. But Gero3D's cast was so comfortable, I didn't feel any itching at all! I even went swimming in the sea.
Thanks to your cast, I was able to go on the family vacation that was planned in advance. The cast allowed me to travel, swim, and do everything!
It was very comfortable, and the pain stopped. I rate my recovery experience 5/5 and highly recommend it to anyone who wants to heal with maximum comfort.
